5 Claims.

The invention herein disclosed relates to a window constructionespecially suitable for ships, and in particular to a weathertightwindow construction in which the window-pane is readily removable.

Commonly, windows of this type include a frame having an openingtherethrough, a window-pane movable in a plane parallel to the frame,window-pane-guideways for guiding a window-pane in movement between openand closed positions thereof, and traversing mechanism for moving thewindow-pane. In certain constructions the window-pane is movablelaterally of the frame for pressing the window-pane, in the closedposition thereof, firmly against a gasket mounted on the frame aroundthe opening therethrough. When the window-pane is thus pressed againstthe gasket there is a weather-tight closure of the window openingthrough the frame. For certain ships it is desirable to have a windowconstruction such that the window-pane may be readily and easilyremovable. This is particularly important on battleships as the window-panes, when mounted in the window, are frequently broken duringtarget practice, and it is an object of this invention to provide awindow construction adapted for this purpose.

In accordance with the invention, a window construction of the typereferred to includes guideways for the window-pane which are secured tothe frame and embrace the side edges of the window-pane. Each suchguideway comprises a section which is readily removable to release thewindow-pane from the guideway. The windowpane is also readily and easilydisconnected from the window-pane traversing mechanism. For example, inone form of window constructed in accordance with this invention, twoside, windowpane guideways, which are slidably mounted on the windowframe for lateral movement with respect thereto, embrace the side edgesof the window-pane. Each guideway includes a removable section adjacentthe window opening through the frame, which may be removed to free thewindow-pane. Embracing each removable section of the guideways there isa bracket which is mounted on the frame and which carries mechanism formoving the guideways laterally to the frame. The window-pane traversingmechanism includes a carriage moved by the traversing mechanism and aclamp embracing an end edge of the windew-pane is releasably connectedto the carriage.

Such a window construction is illustrated in the accompanying drawingsin which Fig. 1 is an elevation of the window;

Fig. 2 is a sectional, end elevation taken along the irregular line 2--2of Fig. 1;

Fig. 3 is a fragmentary, sectional plan taken along the line 3-3 of Fig.1; and

Fig. 4 is a fragmentary, sectional elevation window opening which isdefined by inboard and outboard lateral flanges la and lb. The frame issecured in a vertical position to the plating of the vessel with theoutboard flange lb extending through the plating. Brackets lo and Id onoppositesides of the frame, below the window opening, extend laterallyof the frame and support a cross bar 2 which supports the windowpanetraversing mechanism.

The window-pane traversing mechanism is mounted in a bracket 3 securedto the cross bar 2 and includes a vertical, threaded shaft 4 journaledin the bracket at its upper end and at its lower end in a bar 5extending between two angle irons 6 and I secured to and extendingdownwardly from the bracket 3. On the upper end of the shaft 4, there ismounted on the shaft a gear 8 for rotation with the shaft. The gear 8meshes with a gear 9 mounted on a stub shaft Ill having one end squaredand extending through the cross bar 2. Fitted on the squared, protrud- Ling end of the stub shaft I0, there is a handle H by means of which theshaft 4 may be manually rotated. When rotated, theshaft 4 effectsvertical movement of a nut l2 threaded on the shaft and restrainedagainst rotation therewith dow-pane and the metal clamp. The tongues Maand Mb are held in the slots in the carriage 13 by thumb screws l1 andI8, which extend through transverse openings in the carriage and arethreaded into the tongues.

The window-pane and thecarriage l3 move vertically in vertical,channel-shaped guideways l9 and 20 mounted on each side of the frame andwhich embrace the side edges of the windowpane. Each vertical guidewayincludes two sections, an upper section a and a lower section b.

vide a mounting which permits limited lateral and pivotal movement ofthe lower section of the guideway. The section 201) of the guideway 20is similarly mounted and the two .lower sections lab and 201) areconnected together by cross bars 21 and 2B.

The flange la of the frame carries an inwardly extending rubber gasket29 against which the window-pane may be firmly pressed to provide aweathertight closure. The upper sections of the guideways may be movedlaterally of the frame to press the window-pane against the gasket or tomove the window-pane away from the gasket. The mechanism for moving theupper section of a guideway consists of a pair of thumb screws mountedin brackets extending from the frame. Two such brackets 30 and 3| areprovided for the section Illa and similar brackets 32 and '33 for thesection 26a. The brackets 30, 32 and 33 and the arrangement thereof areidentical with the bracket 3| which is channel-shape in cross section.One of flanges am of the bracket is secured by rivets 34 to the frame I;the web 3H) of the bracket extends perpendicular to the frame I and aflange 3lc extends parallel to the frame lso that the guideway isreceived between the flanges 3la and Mo and abuts against the web 3lb.In an internally threaded opening through the flange 3lc there is athumb screw 35 having a handle 36 on one end and an enlarged round head3'! formed on the opposite. end. A grooved plate 38 is secured to theside of the guideway and forms a pocket with the guideway which receivesthe head 3'! of the thumb screw, a constricted slot formed in the plate38 receiving the shank of the thumb screw. The guideway is thus securedto the thumb screw against relative movement lateral to' .thev frame.However, the thumb screw and guideway may be disconnected by moving theguideway longitudinally- The guideways are thus removable and are soremoved when it is desired to remove the windowpane. When it is desiredtoremove the window pane, the thumb screws in the brackets 30, 3|, 32and 33 are turned to move the guideways and the Window-pane away fromthe gasket 29. The studs 2! and 23 are removed and the guideway sectionsl9a and 200. are removed by lifting them vertically. The window-pane maybe disco-nnected from the window-pane traversing mechanism by moving thecarriage l3 to its uppermost position, in which position it'will bedirectly behind the oross-bar '2 and the thumb screws l1 and I8 alignedwith openings through the cross bar 2. The openings are normally closedby movable covers 39 and 40 respectively, which may be swung aboutpivots 4| and 42 to give access to the thumb screws. With the thumbscrews removed, the window-pane can be easily slipped out of the frame.

From the above description of the embodiment of the inventionillustrated in the drawings, it will be apparent that there is provideda sturdy window construction in which the window-pane can be readily andeasily removed without the aid of tools. This is an important advantagein windows of this type.

It is obvious that various changes may be made by those skilled in theart in the details of the embodiment described above within theprinciple and scope of my invention as expressed in the appended claims.
